A responsive user interface. --- #### **4. System Design** ##### **4.1 Architecture** - **Frontend**: React.js, Zustand, Tailwind CSS. - **Backend**: Node.js, Express.js. - **Database**: MongoDB Atlas. - **Hosting**: Vercel (frontend) and Render/Heroku (backend). ##### **4.2 Data Flow** 1. User actions on the frontend trigger API calls to the backend. 2. Backend processes requests and interacts with MongoDB. 3. Frontend updates the UI based on the backend responses. --- #### **5. Functionalities** 1. **Authentication**: - User signup, login, email verification, and password reset. 2. **Task Management**: - Add, view, edit, delete, and mark tasks as completed. 3. **Data Persistence**: - Secure storage using MongoDB. --- #### **6. Development Approach** 1. **Planning**: Requirements gathering and wireframe design. 2. **Frontend Development**: - React components for UI. - Integration with REST APIs. 3. **Backend Development**: - REST APIs using Express.js. - JWT for secure authentication. 4. **Testing**: - Unit and integration testing for API and UI. 5. **Deployment**: - Hosted frontend and backend on scalable platforms. --- #### **7. Technology Stack** - **Frontend**: React.js, Zustand, Tailwind CSS, Axios. - **Backend**: Node.js, [login to view URL], Mongoose. - **Database**: MongoDB. - **Tools**: Postman (API testing), GitHub (version control). --- #### **8. Challenges and Solutions** 1. **Challenge**: Ensuring secure authentication. - **Solution**: Used JWT and Bcrypt for password hashing. 2. **Challenge**: Cross-device data consistency. - **Solution**: Leveraged MongoDB Atlas for cloud-based data storage. --- #### **9. Future Enhancements** - Adding a calendar view for tasks. - Push notifications for task reminders. - Sharing tasks among multiple users. --- #### **10. Conclusion** The "Todo_Renewed" project demonstrates a scalable, modern web application with essential task management features.

Introduction** This document provides the wireframe design for the "Todo_Renewed" project, highlighting the layout and navigation flow of the web application. --- #### **2. Wireframes** 1. **Landing Page (Home)** - **Header**: Logo, navigation menu (e.g., Login, Signup). - **Main Section**: - Welcome message. - Call-to-action (e.g., "Get Started" button). - **Footer**: Links (e.g., About, Contact). 2. **Signup Page** - **Header**: Logo. - **Form**: - Input fields: Name, Email, Password, Confirm Password. - Submit button. - Link to login. 3. **Login Page** - **Header**: Logo. - **Form**: - Input fields: Email, Password. - Submit button. - Forgot password link. 4. **Dashboard** - **Header**: Logo, Navigation bar (e.g., Logout). - **Main Section**: - List of todos displayed with title and status. - Buttons: Add, Edit, Delete, Mark as Completed. 5. **Add/Edit Todo Page** - **Header**: Logo. - **Form**: - Input fields: Title, Description. - Buttons: Save, Cancel. --- #### **3. Design Guidelines** - **Color Palette**: Minimal and clean design using Tailwind CSS themes. - **Typography**: Readable fonts with appropriate sizes for headings and text. - **Responsiveness**: Adjust layouts for mobile, tablet, and desktop views. --- This wireframe design serves as a blueprint for the development and ensures a seamless user experience. ### **Architecture Design Document for Todo_Renewed** --- #### **1. Introduction** The "Todo_Renewed" project is a web-based application designed for task management. It uses the MERN stack (MongoDB, [login to view URL], React.js, Node.js). This document outlines the architectural components, their relationships, and interactions. --- #### **2. System Architecture Overview** The system is designed as a **three-tier architecture**: 1. **Frontend Layer**: - Technology: React.js - Role: Provides user interface and client-side logic. - Communication: Sends HTTP requests to the backend API. 2. **Backend Layer**: - Technology: Node.js, [login to view URL] - Role: Serves APIs, handles business logic, and manages user authentication. - Communication: Processes API requests from the frontend and interacts with the database. 3. **Database Layer**: - Technology: MongoDB - Role: Stores user data (authentication, todos, metadata). --- #### **3. Component Description** 1. **Frontend Components**: - **User Interface**: - Developed using React.js and styled with Tailwind CSS. - State management via Zustand. - **Authentication**: - Login, registration, email verification, and password reset handled through API calls. - **Task Management**: - CRUD operations for todos using REST APIs. 2. **Backend Components**: - **APIs**: - **AuthController**: Manages user signup, login, and password reset. - **TodoController**: Handles CRUD operations for tasks. - **Middleware**: - `authMiddleware`: Secures protected routes using JWTs. - `errorHandler`: Handles exceptions and responses. 3. **Database**: - **Users Collection**: - Fields: `_id`, `email`, `passwordHash`, `isVerified`. - **Todos Collection**: - Fields: `_id`, `title`, `description`, `completed`, `userId`. --- #### **4. Interaction Flow** 1. **Authentication Flow**: - User inputs credentials → React sends a request to `/auth/login` → Backend verifies credentials → Returns JWT → React stores JWT for session management. 2. **Task CRUD Flow**: - User requests task operation → React sends API request → Backend processes operation and updates MongoDB → React updates UI. --- #### **5. Deployment Architecture** - **Frontend Hosting**: Deployed on platforms like Vercel or Netlify. - **Backend Hosting**: Hosted on AWS, Heroku, or Render. - **Database**: MongoDB Atlas for cloud-based storage. --- This architecture ensures scalability, modularity, and maintainability, supporting cross-device synchronization and secure user interactions.
